Intermittent rattle in engine compartment - 2004 Z4 3.0

[cantdrv55]

Kind of sounds like a loose heat shield but I cannot locate the source because it's intermittent. Has anyone chased down a rattle under the hood yet?

I have a rattle/knocking noise when going over uneven roads, it seems to be coming from the front underneath the car.
There are a couple of heat shields below the drivers seat area. Mine were loose and which I thought was the cause, so last week I fixed them back up but the noise is still there.

Could it be the drop links?
That's what I'll look at next.

Anyone else shed some light??

Did you locate the problem?
Mine was a drop link, had it changed today.

Did see a post with some one chasing a rattle for ages and it turned out to be a loose factory strut brace.
Was left loose after a plug change.

I had this and I found that the heat shield on the top of the drivers side engine mount had snapped and was wedged in between the steering and the mount
